Job Number 260010

The yellowed plastic crystal on this on caused corrosion on the hands. I may be able to clean this up, we'll see. Other internal parts were OK.

Old formulations of plastics did this as they also turned themselves green, yellow or even sometimes blue. Modern watch crystal replacements, that aren't glass, are plexiglass and don't have this problem.

Elgin serial number 20361371 is a grade 313, 16 size, 15 jewels, made about 1918.
